Product details

40-position mezzanine header, 1.27 mm pitch

The 87849-120LF is the 40-position dual-row member of Amphenol ICC's Rib-Cage III board-to-board header series, designed for mezzanine stacking at a 6.42 mm mated height.

Board-stacking fit and footprint

The 1.27 mm pitch and 1.27 mm row spacing place the 40 positions in a dense footprint that routes between two adjacent PCB layers without a via-in-pad. The 6.42 mm mated stack height suits mid-height mezzanine gaps where a 5 mm connector is too short and an 8 mm connector wastes z-height.

Frequently asked questions

Who supplies 87849-120LF and how is it quoted for volume purchases?

Sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. The 40-position dual-row 1.27mm pitch specification matches the Rib-Cage III series footprint — confirm the mating receptacle pinout and board stack height before committing the BOM quantity.

What compliance documentation does Amphenol provide for the 87849-120LF?

The housing material carries a UL94 V-0 flammability rating; no RoHS or REACH compliance designation appears on the available record for this variant. Confirm full REACH/RoHS status with the manufacturer prior to finalizing environmental compliance requirements for the end assembly.
